Be it known that I, DAvm ANDERSON, en-

in or Relating to Burners for Incandescent specification.

t has hitherto been prop'osedzto employ l .brations to an incandescent burner and also= in various ways radially-arranged springs for the prevention of transmission of lateral v1- to use radially-arranged selasticy tubes conbend under verticalivibrations and which veying gas tothe .burner for this purpose; but

it has been found 'that none ofthese devicesI "are satisfactory or convenient, because asap- 'these and other difiiculties and toavoid the,`

'use of flexible gas-supply pipes.

This invention, therefore, consists in se arating the burner-head, together with t e 'Whole or apart of the mixing-tube, from the -gas-supplynipple `and the yfixed parts which t e latter is carried and in supporting the said vseparated parts from the xed parts bymeans of three'or more symmetrically-disposed springs acting.` by vboth their axial and.

transverse resiliency'and of such elasticity 'and' stiffness that they-will absorb both vertical vibrationsand lateral vibrations inall radial planes'through the axis of the burner andyet of such compact form and disposition that they do not substantially obstruct the i light.

lferred to employ springs of elastic wire closely coiled, so as to form resilient screws which are axiallyresilient under lateralxvibrations in any plane -radial tothe burner,` the ends ofy uthe springs .being supported in`screwed sockets and adjustedbyy rotation.

Figs. 3, 4, 5, and 6' are views illustrating several attaching devices for the supportingsprings. Fig. 7 is a vertical section, partly in elevation, of Van inverted burner; and Fig, 8 isfa plan view of the upper portion of the burner. shown in Fig. 7 .i

` In the figures, a is a gallery supportin the globeor chimney and itself supported om4 a suitable base-plate b by pillars a. Through the plate b'projects a gas-supplyj et or nozzle c, the said plate screwing thereonto. Within the said `gallery a and concentric therewith is disposed a tubularpart d, which supports or constitutes the burner member d and carries the mantle-rod and mantle d2. The inner tubular part is or maybe increased in diameter at its base, as at d3, and is suspended overthe gas-jet c without connection therewith'and forms the gas and air mixing chamrber,'to vwhich air is admitted by holes d4 in the Y' usual manner. from the pillars a: by means of symmetricallydisposed radial springs e, e awhich, as before described, act by both their axial and .transf verse resiliency and are of such elasticity and stinessthat they will absorb both .vertical-and lateral vibrations in all planes radial to the axis of the burner, said springs being valso of such compact `form that they not substantially obstruct the light. burner as shown in Figs. l and 2` and of the proportions `herein given I iind very satisactory results are obtained if the springs are madeof steel music-wire,gage No. 8.020 or 11.026-, or thereabout. It is to be understood that I do not bind myself to this particular type of wire. A

Thespringsmay be iixed in any suitable manner; but the drawings show an approved form, wherein 'the screws-are formed in the manner of resilient` screws and the inner tubular member is vformed with holes f,- corresponding with other holes in the pi lars a". The said holes are tapped with a screw-thread of the same or approximately the same pitch as the winding of the resilient screws or'- a itch to which the said Winding will conform.

n -assembling the arts the .resilient screw is vscrewed through. t e hole inthe pillar until it reaches across the intervening space landis screwed into the hole in the inner member d.- The ends of the spring may be left open, so that air may pass therethrough, ortheapertures may be closed" by-'suitable studs or The member d is supported v i plugs. This method of fixing the resilient members is more clearly shown in Fig. 3, which is a section through the hole in the pillar a and member d, drawn to a larger scale. In a modified form shown in Fig. 4, which is a section of the lower part of member d and spring e, (also to a larger scale,) the spring e is screwed onto a stud g, which is then screwed into the hole f4 in the member d.

If required, however, the studs may be formed in one with the member d and tapped as required. Fig. 5 is a similar View to Fig. 3, showing how the resilient member e may be fastened by means of screwing the same onto a stud g similar to that shown i'n Fig. 4 on the member d and also secured to thepillar c by a similar studV g, which may be formed with a suitable head g2, by which the tension or position of the resilient member@ may be adjusted to properlycentralize the member d. Fig. 6 is another view, similar to Fig. 3, showing a modified form wherein the resilient member e may be screwed into recesses h and h, respectively, in the pillar a and the member d. The recesses are shown as being formed with threads for screwing in -the resilient member e, and so securing the desired firm attachment; but, if required, by makin the resilient member a reasonably tight t as regards diameter and making them of such length as to be in compression when in position the screw-thread might be omitted. It may be mentioned, however, that a great advantage of' the forms shown in Figs. 1, 2, and 3, where no studs are used, is that the resilient members can be of short length and the surrounding parts can be more compact, and, further, the springs and parts may be more easily assembled and the central member d more quickly centralized, as it is only necessary to screw in the resilient members through the respective holes while the central member is held in position and then cut off any projecting portion of the resilient member, or, if short lengths are used,

,they can conveniently be screwed back and` forth until correct.

Fig. 7 shows the application of the invention to an inverted burner, wherein the resiliently-supported member consists of arms c2, carrying the gallery a, mounted upon the depending tubular part 7c, which supports the mantle and forms the burner. The part 7c is supported at its upper end from arms or members c by means of resilient members e, suitably formed and fixed, as before described, to the fixed part b of the burner.

Fig. 8 shows the upper part of the burner of Fig. 7 in plan. A screen or shield of refractory material may be disposed just below the springs e to further protect them from the heat of the burner. By this construction the resilient members are kept cool by the draft Yof air to the burner and protected lfrom the heat by their position.

Resilient members of the form and disposition herein specified possess considerable advantage in their action over springs in the forms and positions hitherto adopted for antivibration purposes, because in the improved construction they Will absorb both lateral and vertical vibrations in all radial planes, and so allow freedom of motion in all directions; but they nevertheless possess sufficient strength to form a good and stable support for the burner.

find springs such as referred to when formed a comparatively tight fit either upon the outer surface of a stud or the. inner surface of a hole can by being put in position by a screwing motion obtain an effective grip sufficient to prevent their being withdrawn other than by a reversal of the screwing action.

It will be understood that the spring-supported member d may be modified in form to adapt it for use with any existing form of burner. For instance, I may construct this member as a separate sleeve or socket adapted for attachment to existing burners and serving to resiliently support the air-mixing chamber and burner-head.

I claim l. An attachment for incandescent Igaslighting, comprising supporting and supported members, and radial helical springs engaging said members and sustaining the supported member, at least one of said engagements being adjustable, substantially as described.

2. An attachment for incandescent gaslighting, comprising supporting and supported members, and radial helical springs adjustably enga ing both of said members, substantially as escribed.

3. An attachment for incandescent gaslighting, comprising supporting and supported members, radial helical springs adjustably engaging one at least of said members and sustaining the supported member, and a burner-head carried by the supported member, substantially as described.

4. An attachment for incandescent gaslighting, comprising supporting and supportved members, and radial helical springs sustaining the supported member, the end helices positively engaging said members, substantially as described.

5. An attachment for incandescent gaslighting, kcomprising supporting and supported members, and radial helical springs sustaining the supported member, the end helices adjustably engaging one at least of said members, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DAVID ANDERSON.
